T 0 all whom t may concern:-

Be it known that we, JAMEs V. RIDLEY, Sr., and ALBERT Gr. RiDLELvcitizens of the- United States,

Jackson and State of Arkansas, 'have invented certain new and useful lm 'rovements in Tell-Drilling 'lools, of-

Our invention relates to improvements in well drilling tools,

' and arrangements herein described and claimed,

A:An objectof our invention is .to provide atool'which. will facilitate lthe sinking. of

Artesia'n wells orl other small bore wells.

A further object of o'i1r. invention is'to provide a drill ,point which is designed to be 'rotated and by means'of which the earth is pressed outwardly, thereby facilitating the entrance of-'thedrill p'oint proper A further object of our invention is to provide ai device of thel type described which particularly is designed to be left in position after the well is bored, thereby doing away with the' necessity of removing the ,drill point after the operation is finished and againreplacfinthe point. -V he other objects of 'the invention will.

the following specification, and the invention will be out vin 4the appended appear in the novel features of pointed claims.

Uur invention is illustrated in the accompanying drawings forming part of lthis applicaton and in which-1 Figure lisa side view of the device; Fig.

- 2 is a longitudinalfsection therethrough showing the point in-'a well,and Fig.- 3 is a section along thel lineB-Sof Fig. l.

ln carrying out our invention we'provide a body portion 1 which is preferably made of metal of any suitable kind.l This body i the manner 415 cut, cast, or otherwise shaped. in shown in the drawings.

The upper surfaces o these blades are shown at 3?- and 4* respetively and it will be noticed that they are portion is extended in a continuous spiral toward the depth which has been apparatus is left in zontal lines, or in other words, the faces 3? and'residei'its of Newport', in

furthermore benoted that these faces'X and 4.* decrease in width towardvthe upper endof'the tool. 4Another fact to which We wish 'to call attention is that thegreatest -diameter of thetoolis maintained through the by this lconstruction theblades have'lower spirally extended-surfaces inclined' to the i vertical. These inclined surfaces are shown at 5, the inclination of thesel lower' ysurfaces becoming more nearly vertical as the top is approached, ,en ncl finally becoming coin-I pletely vertica l At 6 we have'indicated a 'portion of the ing'headby extending th boring head as said extension having -a reduced diameter to enter the pipe 6 'and securing the pipe in'any suitable mannersuch as b y a pin orbolt 7; The pipe 6 may be provided with openings 8 and may be covered with a screen 9 in the usual manner.

From the foregoing description of the various parts of the device, the peration thereof may be readily understood. Instead of forcing the boring tool into tine ground in the-ordinary manner, tliepipe 6 is rotated in any suitable manneig Aand the tool is screwed into the ground after the manner of an auger. The tool, however, in the ymanner of the ofdinary auger, nor does it have t'he functions of the same as will, be apparent from 1the following con-l siderations The inclined surfaces"v and 4"' will tend to force the tool into the ground but unlike an augei` the lower inclined surfaces 5 will tend vto force the dirt outwardly; that is ilo say, to press it out in a lateral direction. lt is not intended to remove the material and in this it differs from the auger.

It will be seen that the greatest diameter of the -tool is greater than that of the pipe 6f; little if 'any frictional rlhe pipe 'forms 'as will be seen an operating member for rotating the boring point.

After the'well has been drilled to the or tool forms a substantial base .upon which the pipe'rests a d the water or other 'Huid is not made successive spirals except at thebottom 4inein-v ber or pointQ. It will be further seen Lthat.'5

This may be' secured to the boi-'f determined upon, the place. The boring 'point il., A l
